Autosomal recessive spino-olivo-cerebellar degeneration without ataxia.

Five adult siblings from a sibship of ten suffering from an external ophthalmoplegia with a spastic paraplegia are reported. In addition, optic nerve atrophy was present in three of the patients and dementia in two; extrapyramidal signs and cerebellar ataxia were found only in one patient. Contrary to earlier studies of patients with comparable neurological signs the pattern of inheritance was autosomal recessive. Neuropathological investigation of the index case, who had never shown ataxia, nevertheless showed demyelination of the spinocerebellar and the olivocerebellar pathways, and also a severe loss of Purkinje cells, of cells in Clarke's column and in the inferior olives. The dentate nucleus was severely gliotic but showed no cell loss. Earlier neuropathological investigations of this disorder, but with an autosomal dominant heredity, were incomplete. It is concluded that the five siblings of this family have a unique autosomal recessive disorder, which should be considered a distinct entity.

Autonomic nerve calcification and peripheral neuropathy in olivopontocerebellar atrophy.

This report concerns an unusual form of olivopontocerebellar atrophy (OPCA) of adult onset, inherited as an autosomal dominant. We examined 5 patients in one generation and performed neuropathological investigations in 3 of these. The clinical and pathological features were different from those of OPCA types I to V. Apart from olivopontocerebellar degeneration, there was dementia in 4, massive atrophy of the spinal cord in 3, and focal degeneration of the optic nerves in at least 1 case. The most remarkable findings were, however, the involvement of the peripheral nervous system and the abundant intrafascicular calcification in sympathetic nerve fibers and in their ganglia.

External ophthalmoplegia, juvenile parkinsonism and axonal polyneuropathy in two siblings.

In one of two siblings a clinical disorder was described, consisting of a slowly progressive juvenile parkinsonism with extensor plantar responses, external ophthalmoplegia with severe ptosis and a motor and sensory polyneuropathy. The younger sibling had only juvenile parkinsonism, Unilateral ptosis and a motor and sensory polyneuropathy. Their father was neurologically normal except for a unilateral ptosis. There did not seem to be consanguinity in this family.

Hereditary sensory neuropathy, a new type.

Two brothers with a new type of hereditary sensory neuropathy are described. The main clinical feature is late onset sensory ataxia without ulcerating acropathy or other autonomic abnormality. The older patient also has oculomotor dysfunction and extensor plantar responses.

An unusual form of spinal muscular atrophy with mental retardation occurring in an inbred population.

Three sibs are described suffering from hereditary non-progressive spinal muscular atrophy with non-progressive mental retardation. One of them had in addition signs of pyramidal tract involvement. Muscular weakness was more pronounced proximally than distally and the neck muscles were severely involved. Th.ey all had small skulls and several associated congenital malformations were observed including syndactyly of the left hand in 1 patient. The patients belong to a small inbred community in the Netherlands. Erythropoietic protoporphyria was also present in the family but segregated independently. This combination of "congenital" mental retardation with "congenital" non-progressive spinal muscular atrophy is believed to represent a new syndrome, caused by a rare recessive gene.
